I'm running into a little bit of the inconsistency in systray icon sizes as we're working to try to improve the systray icons.
http://wstaw.org/m/2014/09/21/5.1_systray_scaling_bug.png The icons are still a WIP so please ignore that for the moment. All the icons are 16x16 sitting on a padding rect in the svg. The only way I can get all the icons to properly render at 16x16 is to use a 32x32 padding rect for the example battery icon and a 24x24 padding rect for the klipper icon (the first screenshot). If I put them both on a 24x24 rectangle the battery icon appears to get scaled up resulting in both a bigger icon, and the icon no longer aligned to the pixel grid resulting in bluriness (the second screenshot) for the battery icon but a sharp klipper icon. The other downside is that with such a big padding rect for the battery icon, where it is used elsewhere the icon is really small. The same thing happens with the network icons as the battery icons. I'm not sure how to tell how the icon will be used, so I'm not what rule to follow to ensure the icon sizes are rendered consistently. I was going to file a bug, but I wasn't sure so I thought I'd chime in here. Hope this helps, Andrew On Mon, Sep 15, 2014 at 12:56 AM, Marco Martin <notm...@gmail.com> wrote: > On Friday 12 September 2014, Kai Uwe Broulik wrote: > > Hi, > > > > One of the problems is that most of the tray icons use a Plasma IconItem > > which follows the icon sizes (16, 22, 32, 48, ...) whereas a custom item > > does not. > > > > This is also the reason why battery and network usually appear in a > > different size since they're using SvgItem which doesn't have this magic. > > > > Imho that needs fixing in systray. > > I'm not sure that can be fixed in the systray, because it's still important > for the clickable area to reach the screen edge(fitts law and all that > jazz), > so the actual item size should still touch the containment edges. > > and is the same thing for applets just in the panel, you would have the > same > problem, so in order to retain flexibility custom compactrepresentation > items > should still compute their size... > > What about a function > units.roundToIconSize(size) ? > > would still be manual, but very quick to do > > MouseArea { > //the rootitem that goes to the edget > > Item { > //whatever is graphics goes here > width: units.roundToIconSize(parent.width) > height: width > anchors.centerIn: parent > } > > } > > -- > Marco Martin > _______________________________________________ > Plasma-devel mailing list > Plasma-devel@kde.org > https://mail.kde.org/mailman/listinfo/plasma-devel >
